Medium-frequency DC qhov chaw vuam tshuab tau dhau los ua qhov tseem ceeb hauv ntau qhov kev lag luam, muab cov kev daws teeb meem zoo thiab meej rau ntau yam kev siv.Lub plawv ntawm cov tshuab no nyob hauv lawv cov electrodes, uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem vuam.Hauv tsab xov xwm no, peb yuav delve rau hauv cov ntsiab lus tseem ceeb ntawm cov tshuab electrode rau nruab nrab zaus DC qhov chaw vuam tshuab.
- Kev xaiv khoom: Kev xaiv cov khoom siv electrode yog qhov tseem ceeb hauv kev ua kom lub neej ntev thiab kev ua haujlwm ntawm lub tshuab vuam tshuab.Electrodes feem ntau yog tsim los ntawm cov ntaub ntawv xws li tooj liab, tooj liab alloys, thiab refractory hlau.Tooj liab yog ib qho kev xaiv vim nws cov hluav taws xob zoo heev thiab thermal conductivity, nrog rau nws tsis kam hnav thiab tsim kua muag thaum vuam.
- Electrode Geometry: Kev tsim ntawm lub taub hau electrode yog qhov tseem ceeb rau kev ua tiav zoo ib yam thiab zoo welds.Ntau yam geometries, xws li tiaj tus, dome, thiab taw tes, yog siv nyob ntawm daim ntawv thov.Lub electrode geometry yuav tsum tso cai rau kev sib cuag nrog cov workpieces thiab muaj zog hloov pauv.
- Txias Systems: Medium-frequency DC qhov chaw vuam ua kom muaj cua sov ntau ntawm cov lus qhia electrode.Txhawm rau tiv thaiv overheating thiab tswj kev ncaj ncees ntawm cov electrodes, cov tshuab ua kom txias tau ua haujlwm zoo.Dej txias yog ib txoj hauv kev zoo, thiab nws yog ib qho tseem ceeb rau kev saib xyuas thiab tswj cov txheej txheem txias kom tsis txhob muaj kev puas tsuaj rau thermal.
- Kev tswj hwm: Lub zog siv los ntawm cov electrodes mus rau cov khoom ua haujlwm yog qhov tseem ceeb rau kev ua tiav qhov muaj zog thiab zoo sib xws.Cov tshuab vuam niaj hnub no siv cov txheej txheem tswj kev tswj xyuas kom ntseeg tau tias qhov kev xav tau raug tswj xyuas thoob plaws hauv cov txheej txheem vuam.
- Alignment thiab Precision: Kev sib raug zoo ntawm cov electrodes nrog cov khoom ua haujlwm yog qhov tseem ceeb kom tsis txhob muaj qhov tsis sib xws thiab qhov tsis xws luag.Precision tswj systems thiab sensors yog siv los xyuas kom meej tias cov electrodes yog raug positioned ua ntej thiab thaum lub sij hawm vuam txheej txheem.
- Electrode Hnav khaub ncaws: Sij hawm dhau mus, electrodes tuaj yeem hnav los yog ua paug, cuam tshuam rau qhov zoo ntawm vuam.Kev hnav khaub ncaws electrode tsis tu ncua, uas cuam tshuam nrog kev rov ua dua lossis hloov kho cov lus qhia electrode, yog qhov tseem ceeb los tswj kev ua haujlwm vuam.
- Kev soj ntsuam thiab kev tawm tswv yim: Kev saib xyuas lub sijhawm tiag tiag ntawm cov txheej txheem vuam yog qhov tseem ceeb rau kev tswj kom zoo.Cov sensors thiab cov lus tawm tswv yim muab cov ntaub ntawv ntawm yam xws li tam sim no, qhov hluav taws xob, thiab hluav taws xob kub, tso cai rau cov neeg ua haujlwm kho kom tsim nyog rau cov txiaj ntsig zoo.
- Kev kho thiab tshuaj xyuas: Kev saib xyuas kom zoo thiab kev tshuaj xyuas ib ntus ntawm electrodes yog qhov tseem ceeb los tiv thaiv lub sijhawm poob qis thiab ua kom lub neej ntev ntawm lub tshuab vuam tshuab.Kev kuaj xyuas tsis tu ncua rau kev hnav, kev puas tsuaj, thiab kev sib kis yuav tsum yog ib feem ntawm kev saib xyuas.
Hauv kev xaus, kev nkag siab cov ntsiab lus tseem ceeb ntawm cov tshuab electrode yog qhov tseem ceeb rau kev ua tiav zoo ib yam thiab zoo welds nrog nruab nrab zaus DC qhov chaw vuam tshuab.Kev xaiv cov khoom siv, electrode geometry, cua txias tshuab, tswj kev quab yuam, precision alignment, electrode hnav khaub ncaws, kev saib xyuas, thiab kev saib xyuas txhua yam ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig thiab kev ntseeg siab ntawm cov tshuab no hauv ntau daim ntawv thov kev lag luam.
